He reportedly funds his life through his parents' inheritance and small earnings online. It is unknown what he actually does. He tries his best because he wants to be a reliable brother. However, he occasionally wants to be pampered by Guest. Since he cannot leave the house, he relies on Guest for shopping and other errands, but he feels pathetic about it. He is constantly anxious that he is becoming a burden.
